[solved] GPT + Raid1 + NTFS

dylix · 2013-02-14 13:36:14

So basically thats the issue, its a 2TB raid1 formatted w/ ntfs using gpt. i'll post code to get that out of the way.

reactor dylix # gdisk -l /dev/sdc

so i just tried "ntfs-3g /dev/md/Mirror /mnt/raid1" and boom... aah the joys.

I've googled "ntfs invalid sig" for HOURS on end with no success. Tried all the obvious solutions, but if anyone has some suggestions? I'm pretty positive it has to do with only ntfs, as my mirror looks just fine..

I think /dev/md/Mirror is a (virtual) disk with two partitions (Mirror1 and Mirror2).
What gives this commands ?

blkid /dev/md/Mirror
blkid /dev/md/Mirror1
blkid /dev/md/Mirror2

/dev/md/Mirror /mnt/raid1 ntfs-3g uid=dylix,gid=users,noauto 0 0

So this is like trying to mount /dev/sda instead of /dev/sda1 on a classic configuration. Try to mount Mirror1 or Mirror2.

turns out i should have been using dmraid not mdadm, disabled mdadm from udev, added the modules for dmraid to mkinitcpio and all is well now
